MACHINE FOR ATTACHING FLY-COVERS TO BOXES.

SPECIFICATION forming part of Letters Patent No. 581,513, dated April 27, 1897'.

Application led May 15, 1896. Serial No. 591,626. (No model.)

To all whom t may concern.-

Beit known that I, WILLIAM W. LrsINGnR, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Attaching Fly-Covers to Boxes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in box machinery in which the boxes have paper iiies or interior covers attached to more attractively inclose the contents of the boxes, in many instances the flies being of fanciful Adesigns which require much care and delicate manipulation to properly attach them and without the possibility of smearing them with the attaching-adhesive or mutilating them in the act of attaching.

The general method of attachment has heretofore been by hand, the fly-sheets being stacked and arranged to have each sheet slid back to expose a narrow strip of the next sheet under it, so a number could at one time be brushed with the adhesive mixture, a slow, tedious, and expensive process. With my machine a package of sheets are grasped and firmly held while the adhesive is applied to each sheet separately. lt is then pressed firmly in place without the liability of its being damaged or soiled, and much more rapidly and truly than by the most experienced hand manipulation. l attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation. Fig. 2 is a front elevation. Fig. 3 is a rear elevation. Fig. 4 is a top view. Fig. 5 is a vertical section on line ct h, Fig. 4. Fig. 6 is a detached plan of the table. Fig. 7 is a section of the wiper on line x, Fig. 8 and Fig. 8 is a front fragment of the wiper and wiper-holder. Fig. 9 is a plan of the double pan, and Fig. 10 is an end elevation of the double pan.

My machine has a framework A, and at the front of the machine is a slide 1, guided at each end 2 3 for vert-ical movement, and attached thereto and lying upon it is atable 4. A pin in the slide 1 is inserted into it, the contact being a free lit to enable the table to be lifted easily. Brackets 6 7 upon the front and lugs S 9 upon the back of table 4 securely support it in place upon the slide 1. A removable construction is essential, as tables of different lengths are required for different-sized boxes, as the table is inserted within the box and an easy removal of one length to permit its replacement by another length of table is desirable. An exten sion 10 of table 4 extends inward, it being notched at its front to embrace the table 4 at one side and at each end, and it is supported by a bracket 11, secured at each end to the slide 1 and extended inward under 10. Guides 12 `13 at the ends and 14 at the center limit the insertion of the fly-paper upon the table, the guides being adjustable, having slots 15 in each, and inserted therethrough and into extension 10 are clamping-screws 16 to secure the guides after adjustment.

The slide is supported by levers 17 18, fulcrumed upon a slide-shaft 19. The outer ends of the levers 17 18 are circular and are inserted into slots 2O 21 in slide 1, and wherein they roll. The inner ends of the levers 17 18 carry counterweights 22 23, hung thereon to be easily removed, if desired. At one end of the shaft 19 is fixed a pulley 24, upon which lies a flexible band 25, one end of which is jointedly attached to a lug 26 of a lever 27, and the other end of the band is jointedly attached to an adjusting-screw 2S, inserted through a lug 29 of the lever 27 and having an' adj usting-nut 30, which enables the band to be tightened or loosened. The lever 27 is fulcrumed upon a brake-shaft 31, and its lower ,end rests against a cam 32, secured to shaft 62.

The power is applied to my machine by means of a belt 34, running on a pulley on a driving-shaft 36. The pulley runs loose on the shaft and has a hub 37, on which are lugs 38, carrying knuckle-joint arms 39 to frictionplates 40 inside of the pulley-rim. A sleeve 41 runs on the shaft 36, a feather 42 being let half into the shaft and half into the sleeve. This enables the sleeve to move the shaft with it in its revolutions, while the sleeve can slide IOO freely along the shaft. Aims 43 are pivoted to the sleeve at 44 and to the knuckle-arms 39 at 45. A groove 40 is made around the sleeve, and within it rides a forked arm 47, attached to a rod 4S, the other end of which is pivotally att-ached to a lever 49, fulcrumcd upon a rod-stand 50. The lever 49 has a roller 51 attached to its upper end, which runs against an edge cam 52,secured on the pressershaft 53. The cam has a continuous surface where the roller runs, except at 54, where it is depressed, and into which the roller 51 moves. The lever 49 extends at a right angle at its fulcrum 50 and extends inward and has attached to its end a rod 55, which extends downward near the ioor, on which the stand B, on which my machine rests, is secured. At the lower end of 55 is a treadle 50, which the operator presses down when he desires thc machine to run continuously; otherwise it will automatically stop when the roller 51 drops into the depression 54, which the spring 57 forces it to enter, thereby releasing the clutch. lf the foot-treadle be not pressed down, the machine will automatically stop after one revolution of shaft 53 or two revolutions of shaft 36, they being geared two to one.

On the shaft 3G are pinions 58 59, firmly secured thereto, 5S engaging gear G0 on presser shaft 53, and 59 engaging 0l on cam-shaft 02. Shaft 53 extends outside of the framework A, and at each outer end are attached cranks G3 G4. To the cranks are secured rods G5 66, which reach upward and are journaled at each end of the pressure-bar (57, guided in the extensions GS 09, which are slotted to admit the bar G7. Directly back of the shaft is the shaft 02, already mentioned, on which are secured cams 71.. At the upper part of the framing A is secured a holder-shaft 72, having thereto secured arms 7 74, which reach down and abut the cams 70 71, and springs 77, attached to the framing and bearing against the arms, cause them to remain in contact with the cams 70 71. From the shaft two arms 7S 79 reach forward and are secured to a holder-plate S0, the arms being attached to the shaft in such a manner as to be movable around the shaft and held so as to perw mit of this adjustment, as shown in the draw ings, set-screws 81 being used.

The holder-plate presses down the fly-sheet while the adhesive is applied and raises up to allow the sheets removal after the pressure bar 07 has done its work. There are also upon the shaft G2, at its outer ends and beyond the framing, two cranks 82 S3, to which are coupled rods S4 85, which reach back and attach to wi per-arms 87 f ulerumed on shaft 130. At the top 0f the frame and reaching across it is a shaft 8S, carrying a roller 89, which is made to revolve by a belt 90, running over the shaft 62, or a pulley thereon, and over a pulley 91 on shaft 8S.

Under the roller 89 is a pan or receptacle 92 for holding the adhesive mixture, in which the roller 89 is partiallysubmerged, as shown in Figs. 1, 2, 3, and 4. This pan is single, for mixtures such as paste, which may be used cold, but in Figs. 11 and 12 I show a double pan, suitable for such adhesive as glue, which must be kept hot. It has an outer case 93 and an inner case 94, and between these casings I introduce steam at 95 or other more convenient place. The pans are supported upon the framing by a bar 90, passing through their front edge and resting on adjustable bearings 97 98, attached to frames A, and by adjustable supports 99 under their back edge, the support being held to the framing in a manner to permit of its adjustment perpendicula-rly, as by a bolt in a slot-ted hole, as shown. Upon the pan, as seen in Figs. 9 and 10, rest Scrapers 100 101. These also rest upon the roller S9 and scrape off the adhesive to any required length, different widths of Scrapers being used, as required. Attached to the arms SG S7 at their upper end is a wipershat't 102. At the end where arm S7 is attached compressible washers 103 104 adjoin the arm S7, one on each side, and outside of the washers are cella-rs 105 100, one being outside of each washer. Setscrews 107 10S are inserted in the washers, and this enables the washers to be compressed and produce friction against the arm S7, enough to hold shaft 102 firmly after arm 109 leaves slot 111 and before it commences to wipe. Farther in on the shaft than the parts just described is an arm 109, rigidly secured to the shaft and projecting backward, and at its outer end a projection is turned outward. This projection passes back and forth in an open-ended slot 111, formed in an adjustable bracket 112, having slots 11S .114, through which adjusting-screws 110 are passed and secured in the framing. This permits the bracket 112 to be adjusted to control the movement of t-he arm 109, which will hereinafter be described. Either side of the center of the machine-arms 117 11S are secured to shaft 102, reaching forward therefrom, and in the ends of the arms 117 11S farthest rcmoved from the shaft 102 is journaled a wiperholder119, the holder reaching from one arm 117 to the other arm 118. The journal through arm 117 is extended through and beyond the arm and has a thread cut thereon, on which runs a tapped clam ping-nut 120, which presses against the arm 117. This permits the adj ustment of the wiper-holder within the arms. Upon the front of the wiper-holder is the wiper 121, it being attached to the holder 119 for vertical adjustment by adj ustingscrews 122 123, inserted through slotted openings 124 125 in ears 120 127.

The wiper is narrowed at each end where it passes under the arms 117 118 and extends outward to the outer ends of the roller S9. The lower edge of the wiper has a groove 128 throughout its length to serve as a receptacle to hold the adhesive mixture which it gathers from the roller 89.

Having described the mechanism which I IOC IIO

now deem best to employ to accomplish the results I desire, and without limiting myself to the precise construction I have set forth,- I will describe the operation of my machine. A pack of flies 129 are laid upon the table 4, as seen in Fig. 2, which rests upon the slide 1, the guides 12 13 14 regulating the position of the flies, the holder-plate 80 coming upon the top of the pack at about its center. By` means of the slide 1, its levers 17 18, and counterweights 22 23 the pack is held firmly in place. The number of sheets in the'pack of flies can be more or less up to the limit of the depression of slide 1. Now, the power being applied to the machine by means of the pulley 35 and the clutch, which may be of any suitable construction, will turn pinions 58-59 in the same direction as the pulley 35, and the engaged gears 60 61 will be turned the opposite way, as shown by the arrow', and through the medium of shaft 53 the cranks 63 64 will revolve, moving rods 65 G6 and pressure-bar 07 upward. It will be noticed that the cams 71 now force arms 73 74 outward, and through the medium of the shaft 72 arms 78 79. The holder-plate 80 is pressing firmly upon the pack of iiies 129 at the same time the slide 1 and table 4t are locked or held. from moving by means of the cam 32, pressing against the lever 27, which tightens the band 25 and so holds the slide until the fly has been pressed to the box. While the movement I have described was taking place the pinion 59 has moved the gear 61, its shaft 62, and the cranks 82 83 have through their rods 84 85 and arms 86 87 carried the arm 109 into the open slot 111 and by this movement partially revolved shaft 102 and depressed the wiper 121 down to the roller 89, which has been revolved by means of the belt 90, and adhesive mixture has been gathered in the groove 128. The adjustable bracket 112 is provided with a horizontal slot 111, within which runs the projection 110 of arm 109, secured to shaft 102, to which shaft 102 are also secured arms 117 118, which carry wiper 121,all being moved by wiper-arms 86 87. The arms 86 87 move at their upper ends through the arc of a circle whose center is at shaft 130. The arms 109 117 118 are immovably secured to shaft 102, which is yieldingly held to arm 87 by collars 105 10G and washers 107 108, so that as the arms 87 move forward the projection 110 moves horizontally until it has left slot 111, partially revolving shaft 102, thereby carrying the wiper upward and away from the roller 89, as indicated by dotted lines in Fig. l.

As the wiper starts forward the pressurebar 67 commences to move upward and out of the way, and just before the wipe the cam 32 forces the lever 27 and through its attached mechanism presses down on the pack of flies.

.As the wiper moves back the pressu re-bar 67 commences to descend. The attendant now places thebox over the iy-sheet,'the pressurebar 67 descends and forces the box to the fly, and as the cranks 63 64 pass their lower deadcenters the pressure-bar 67 releases the box, the cam 32 releases the lever 27, and the holder-plate 80 releases the ily-sheet and permits it to be withdrawn with its box. As before stated, the shaft 36 makes two revolutions to one of the shafts 53 62, and this slowing down permits time for the attendant to insert and remove the box and at the same time does not run thebelt too slow for best practice. The arms 109 117 118 of shafts 102 are wholly alined by means of the adjustable slot 111 and are held as alined by the compressible washers 103 104i and collars 105 106 until the table 4 is reached, when the act of wiping changes the alinement, which will be again made by arm 109 and its projection 110 in slot 111.
